Function

Peroxiredoxin (Prx) is an antioxidant enzyme. In the Prxs the active-site Cys is oxidized to sulfenic acid byperoxide. The Prxs are divided into typical 2-Cys Prx, atypical 2-Cys Prx and 1-Cys Prx. Prx 5 is expressed in mammalian tissue.

Typical 2-Cys Prx

  • Prx 1 interacts with signaling molecules[1].
  • Prx 2 interacts with signaling molecules[2].
  • Prx 3 interacts with signaling molecules[3].
  • Prx 4 interacts with signaling molecules[4].

Atypical 2-Cys Prx

  • Prx 5 interacts with signaling molecules[5].

1-Cys Prx

  • Prx 6 interacts with signaling molecules[6].

Relevance

Prx are over expressed in cancer tissue[7].
